Pooler and Skippy were trained to march long distances by one military group or another. Most armies train their troops to start a march with your Left foot, not your Right. Which is counter-intuitive if you remember that 90% of the human race is Right-Handed and if left to their own devices would probably start a walk or a march on their Right foot. March Pros know that a person's stride is not balanced; it is not symmetrical. The Army trains you to take 30" strides but while your Right foot might find it easy to keep that 30" stride consistent, your Left foot will not and will tend to take slightly shorter strides of 28" or so. So the Army trains you to Count Cadence - that is elaborate or mark a stride - with your Left foot. You fall into a rhythm of "pegging" the foot or emphasizing it by dropping it harder. This pegging rhythm will "consciously" lengthen your Left-foot stride and keep the 30" from degrading. Otherwise, as every Park Ranger will tell you, people walking long distances will nearly always walk in circles, or more exactly, spirals, as the "shortfall" from the degrading Left-foot stride adds up over distance. In other words, the problem may be solved by becoming conscious of the problem and building yourself a ritual or mnemonic device to compensate for the problem. So Blacks were taught to sing that song on their long journey north and at night to follow the Dipper and during the day to "peg" their left foot to keep them walking in a straight line.
It was the Shekhina who led Israel on its wanderings. During the day she did it as Jehova and her Presence was seen as a Pillar of Cloud. During the night she did it as Elohim and her Presence was a Pillar of Fire. Shekhina is the Miskan, Tabernacle, Tent you see in these images. She is the Burning Thing within the Arc of the Covenant. But then she is the Ark of the Covenant. Semantics is the Science that studies the relationship between Containers and the Thing Contained. It studies Signs and Symbols and how they shake out Meaning.
